wow that is scary, hopefully they fixed this issue on the p4, the plastic does look a little different.One of our local guys had the right stick fall completely inside the controller and lock the phantom in full speed forward flight. He managed to yaw it around and do circles while attempting to get the stick back out again. Eventually it worked loose and he was able to get the aircraft back under control. Turns out all of the threads holding the stick in place had stripped and the stick dropped into the controller body. Scary stuff!
